' TED STATES PATENT FFIC I ORSON W. BRENIZER, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF T0 ANDREW VQG ROUPE I, OF PHILADELPHIA, PENNSYLVANIA.

PAPER-FASTENING DEVICE.

To all whom it may concern:

Be it known that I, ORSON W. BRENIZER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Fastening Devices, of which the following is a specification.

My invention relates to improvements'in paper fastening devices by means of which a plurality of sheets of paper arranged one upon another to form a pack may be fastened together by folding or turning down one corner of the pack and applying the device to the corner folds thus produced.

The object of my invention is to provide a novel, simple and efficient device which may be easily and quickly applied to. and removed from the corner folds without detriment to either the device or the paper folds to which it is applied, and which when applied will securely fasten the corners of the sheets together without liability of accidental separation.-

With the above and related objects in View, my invented device consists of the elements and the combinations ofthem hereinafter described and claimed.

In the accompanying drawings illustratingmy invention Figure 1 is a front view of a paper fastening device showing the preferred form of embodiment of my invention.

Fig. 2 is an end view thereof.

Fig. 3 is a bottom view thereof.

Fig. 4 is a front view of the device in the initial position thereof while bein applied to the folded corner of a pac -of sheets of paper.

Fig. 5 is a View similar to Fig. 4, showing the device in final position after being applied to the folded corner of the paper pack.

Fig. 6 is a rear view of the paper pack with the fastening device applied thereto.

Fig. 7 is a sectional detail on line 7-7 of Fig. 5.

Figs. 8, 9 and 10 are front views of paper fastening devices, showing different forms of embodiment of my invention.

Figs. 11, 12 and 13 are end views of the devices shown in Figs. 8, 9 and 10, respectively.

Referring to the drawings, 2 designates a Specification of Letters Patent.

pin having a free end 3 and having a return bend 4 formed on the other end thereof and extending parallel or substantially parallel to the adjacent portion of the pin 2.

Extending from the return bend 4 and forming a continuation thereof is a loop 5 which extends to and around and embraces the pin 2 and terminates in a straight or substantially straight arm 6 having a free end 8. r

The device is preferably formed of a single piece of wire which extends continuously from the free end 3 of the pin 2 to the free end 8 of the arm 6.

In the constructions shown in Figsgl, 2, 3, 9, 10, 12 and 13 the loop 5 crosses the pin 2 obliquely; and in the construction shown in 'Figs'l, 2, 3, 10 and 13 the loop 5 crosses the pin 2 obliquely from the return bend 4 toward the free end 3 of the pin 2.

In the constructions shown in Figs. 8, 9, 10, 11, 12 and 13 the free end of the arm 6 faces thesame direction faced by the free end of the pin 2; and in the construction shown in Figs. 1, 2 and 3 the arm 6 extends laterally adjacent to the return bend 4 and faces a direction opposite to that faced by the free end of the pin 2. V j .1

In all constructions illustrated herein, excepting the construction shown in Figs. 10 and 13, the parts forming the terminals of the loop 5 are disposed opposite to each other in a direction transversely of the pin 2.

In using my improved fastening device the superposed corners 9 of the sheets 10" to be fastened together are folded or. turned down as shown in Figs. 4, 5,6 and7.. The V fastening device is then placed in the position shown inFig. 4', with the free end of the pin 2 entered between the exposed face of the foremost sheet 10 and the inner face of the inner corner fold 9, and a part of the V device is thus moved to. final position, the

forward branch of the loop 5 and the return bend 4 passes in front of the corner folds 9 and the forward and rearward branches of the loop 5 are sprung apart by the pressure of the bodies of the sheets 10 and their folded corners 9 passing between the branches of the loop 5, the loop 5 thus;

firmly clamping the sheets 10 and their folded corners together. The return bend 4L and the arm 6 are also separated or forced apart against the spring action of the loop 5 and are thus caused to press firmly against the corner folds 9 and the back of the sheets 10 and thus assist in firmly holding the sheets together.

The device may be easily and quickly removed by sliding it back to the position shown in Fig. 4 and then separating it from the sheets of paper.

When the device is in service as shown in Figs. 4, 5, 6 and 7, the engagement of the loop 5 with the outside of the diagonallyeXtending, half-round corner fold 11 and the engagement of the pin 2 with the inside of the half round corner fold 11 prevents displacement of the device transversely of the fold 11 and causes the device to follow. the line of the fold 11 while being applied to or removed from the sheets of paper.

The device is formed of material having sufiicient springiness or resiliency to permit the loop 5 to expand and to permit the pin 2 to move down from the top of the loop 5 to accommodate packs of paper sheets of different thicknesses.

I claim:

1. A paper fastener comprising a in adapted to be inserted into the corner fo ds of sheets of paper, and a loop connected to said pin and embracing the same and adapted to embrace the folds into which the pin is inserted, said pin having a free end permitting it to be inserted into and withdrawn from said folds.

2. A paper fastener formed of a single 7 piece of wire and comprising a pin having a free end and a return bend formed on the other end thereof, and a loop formed on the return bend and embracing said pin, the arm of said loop connected to said return bend being in closer proximity thereto than the other arm of said loop, said pin being adapted to be inserted into the corner folds of sheets of paper, and said loop being adapted Copies of this patent may be obtained for portion of said pin being free to permit it to be inserted into and withdrawn from said folds, and an arm extending from one end portion of said loop and having a free end.

4. A paper fastener comprising a pin adapted to be inserted into the corner folds of sheets of paper, and a loop connected to said pin and embracing the same and having terminal portions opposite to each other in a direction transversely of said pin, said loop being adapted to embrace the folds into which the pin is inserted, and said pin having a free end permitting it to be inserted into and withdrawn from said folds.

5. A paper fastener formed of a single piece of wire and comprising a pin having a free end and a return bend formed on the other end thereof, and a loop formed on the return bend and embracing said pin and crossing the same obliquely from said return bend toward the free end of the pin, said loop being adapted to embrace the folds into which the pin is inserted, and said pin having a free end permitting it to be inserted and withdrawn from said folds. Y

6. A paper fastener formed of a single piece of wire and comprising a pin having a free end and a return bend formed on the other end thereof, a loop formed on the return bend andembracing said pin, and an arm extending from saidloop laterally adjacent to said return bend and hav-' ing a free end facing'a direction opposite to that faced by the free end ofsaid pin, said loop being adapted to embrace the folds into which the pinis inserted, and said pin having a free end permitting it to be inserted into and withdrawn from said folds.

In testimony whereof I aflix my signature hereto. r
